CALL: GET_CLUSTER


xyz

  The coordinates at which the cluster is produced.

  These arguments should not be used if DONE has been set
  to True or OK to False.

  This 3 arguments should be a simple global variables, not
  formulas or constants. The global variables may already exist
  before the procedure is called, in which case their contents
  will be lost, but they may also be an variables that have
  sofar not been used.

  The coordinates are returned as numbers with unit cm.

ecls

  The energy deposited in the cluster.

  This argument should not be used if DONE has been set
  to True or OK to False.

  These energies only have a meaning when using Heed to generate
  clusters. If the mean energy to create an electron-ion pair has
  been entered in the gas section, then for certain track types
  the energy will be set to npair * Epair.

  This argument should be a simple global variable, not a formula
  or a constant. The global variable may already exist before the
  procedure is called, in which case its contents will be lost,
  but it may also be an variable that has sofar not been used.

  The energy is expressed in MeV.

npair

  The number of electrons (and ions) present in the cluster.

  This argument should not be used if DONE has been set
  to True or OK to False.

  This argument should be a simple global variable, not a formula
  or a constant. The global variable may already exist before the
  procedure is called, in which case its contents will be lost,
  but it may also be an variable that has sofar not been used.

done

  This variable is set to True if the present call didn't
  result in a cluster, further calls will not result in
  clusters either.

  Reasons for this to occur are
  - the specified number of clusters has been generated already
  - the particle has reached the end point of the track
  - it has stopped after losing all its energy

  Note the difference between this parameter and OK, the latter
  is set to False if an error has been detected generating the
  clusters, for instance because of buffer overflow in Heed.

  DONE is set to False if a cluster has been generated
  successfully.

  This argument should be a simple global variable, not a formula
  or a constant. The global variable may already exist before the
  procedure is called, in which case its contents will be lost,
  but it may also be an variable that has sofar not been used.
